Atomically thin heat shield protects electronics
Atomically thin heat shield protects electronics
Atomically thin materials developed by Stanford researchers could create heat-shields for cell phones or laptops that would protect people and temperature-sensitive components and make future electronic gadgets even more compact. Excess heat given off by smartphones, laptops and other electronic devices can be annoying, but beyond that it contributes to malfunctions and, in extreme cases, can even cause lithium batteries to explode.

CryoSat conquers ice on Arctic lakes
CryoSat conquers ice on Arctic lakes
The rapidly changing climate in the Arctic is not only linked to melting glaciers and declining sea ice, but also to thinning ice on lakes. The presence of lake ice can be easily monitored by imaging sensors and standard satellite observations, but now adding to its list of achievements, CryoSat can be used to measure the thickness of lake ice - another indicator of climate change.

New quantum trick for graphene: magnetism
Physicists were stunned when two twisted sheets of graphene showed signs of superconductivity. Now Stanford scientists have shown that the wonder material also generates a type of magnetism once only dreamed of theoretically. Sometimes the best discoveries happen when scientists least expect it. While trying to replicate another team's finding, Stanford physicists recently stumbled upon a novel form of magnetism, predicted but never seen before, that is generated when two honeycomb-shaped lattices of carbon are carefully stacked and rotated to a special angle.

On-demand control of terahertz and infrared waves
On-demand control of terahertz and infrared waves
Researchers from the University of Geneva and the University of Manchester have confirmed experimentally the theory of very strong magneto-optical resonance in graphene. The ability to control infrared and terahertz waves using magnetic or electric fields is one of the great challenges in physics that could revolutionise opto-electronics, telecommunications and medical diagnostics.

No escape for mosquitoes
No escape for mosquitoes
Venus flytraps are capable of detecting the movements of even the smallest insects. This mechanism protects the plant against starving from hyperactivity as a new study conducted by scientists from Würzburg and Cambridge reveals. Physically bound to a specific location, plants have to devise special ways to secure their supply of vital nutrients.

Magnetism discovered in the Earth’s mantle: New findings on the Earth’s magnetic field
New findings on the Earth's magnetic field: researchers show that the iron oxide hematite remains magnetic deep within the Earth's mantle / Study published in "Nature" journal The huge magnetic field which surrounds the Earth, protecting it from radiation and charged particles from space - and which many animals even use for orientation purposes - is changing constantly, which is why geoscientists keep it constantly under surveillance.

Washable, wearable battery-like devices could be woven directly into clothes
Washable, wearable battery-like devices could be woven directly into clothes
Researchers have developed washable, wearable 'batteries' based on cheap, safe and environmentally friendly inks and woven directly into fabrics. The devices could be used for flexible circuits, healthcare monitoring, energy conversion, and other applications. The team, led by Dr Felice Torrisi , who recently joined Imperial from the University of Cambridge, have shown how graphene - an atom-thick sheet of carbon - and other related materials can be directly incorporated into fabrics.

Scientists break record for highest-temperature superconductor
University of Chicago scientists are part of an international research team that has discovered superconductivity-the ability to conduct electricity perfectly-at the highest temperatures ever recorded. Using advanced technology at UChicago-affiliated Argonne National Laboratory , the team studied a class of materials in which they observed superconductivity at temperatures of about minus-23 degrees Celsius (minus-9 degrees Fahrenheit)-a jump of about 50 degrees compared to the previous confirmed record.

Adding satnav to turn power grids into smart systems
Adding satnav to turn power grids into smart systems
6 May 2019 An ESA-backed project is harnessing satnav to insert an intelligent sense of place and time to power grids, to provide early warning of potentially dangerous electricity network failures. Four years ago an apparent fire from nowhere forced the evacuation of 5 000 people from central London.

New material to pave the way for more efficient electronic devices
New material to pave the way for more efficient electronic devices
Researchers at the University of Bristol have successfully demonstrated the high thermal conductivity of a new material, paving the way for safer and more efficient electronic devices - including mobile phones, radars and even electric cars. The team, led by Professor Martin Kuball at the Center for Device Thermography and Reliability (CDTR) [MK1] , found that by making an ultra-pure version of Boron Nitride it was possible to demonstrate its thermal conductivity potential for the first time, which at 550W/mk is twice that of copper.

Using 60% less water in paper production
Using 60% less water in paper production
An EPFL researcher has developed a mathematical model for optimizing heat transfer in factories and dramatically reducing water and energy consumption. The model could, in theory, cut water use by 60% at a Canadian paper mill and allow the facility to produce as much as six times more power. Manufacturing consumer goods requires vast quantities of water, heat and electricity.

How to Freeze Heat Conduction
Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy. Every day we lose valuable energy in the form of waste heat - in technical devices at home, but also in large energy systems.

Giving keener "electric eyesight" to autonomous vehicles
On-chip system that detects signals at sub-terahertz wavelengths could help steer driverless cars through fog and dust. Autonomous vehicles relying on light-based image sensors often struggle to see through blinding conditions, such as fog. But MIT researchers have developed a sub-terahertz-radiation receiving system that could help steer driverless cars when traditional methods fail.
